用CRISPR寻找新肿瘤药 - 陈巍基因(32)

欢迎来到【陈巍基因】,我们这个节目,主要是给大家介绍基因组,和临床分子诊断的最新技术进展。

今天要和大家谈的,是用CRISPR方法,来寻找新的、可能的肿瘤药物。

提出这个方法的,是加拿大Donnelly Centre的Traver Hart。Traver Hart把他的这项研究成果,发表在《Cell》杂志2015年12月3日这一期上。论文的题目是《High-Resolution CRISPR Screens Reveal Fitness Genes and Genotype-Specific Cancer Liabilities》。我们这期节目,就主要围绕这篇文章来进行讲解。

文章的核心内容,就是: 1.用CRISPR方法,把几种肿瘤细胞系的几乎所有的基因都做一遍敲除,也就是“Knock out”。 2.然后用高通量测序,来看哪些基因被敲除之后,细胞的生长会受到抑制。 3.接下来,在几种肿瘤细胞系之间进行比较,看哪个基因,是对一个特定细胞系的生长,是必需的,而在别的细胞系当中,这个基因是非必需的。那么,这个基因就可能是治疗这种肿瘤的,潜在的、新的治疗靶点

本视频详细介绍了这种全新的方法,和用这个方法找到的一系列潜在的新药化合物的实例。

家如何利用维基百科

Schulenburg outlines three main reasons why scientists should contribute to Wikipedia; you will learn a lot from the feedback of editors and readers, it is a chance to give back to the Wikipedia community, and your writing will have a much larger audience than in most traditional journals.
